Weird Question About Pans...

The pans I have are aluminum and were purchased years ago. The thing is that over time as they have been washed, they have this odd roughish texture to them and they aren't solid silver anymore. I almost can't describe it, but it's like that have a whitish film on them that won't come off...it's not scratches, though. It almost feels like chalkboard and I can't stand touching them! Odd, I know

Is this normal? I want to get some additional pans, but I'd like ones that won't do that...ones that will stay feeling smooth (except for occasional scratches) and won't feel weird to the touch.
